image quasibound states: image decay and image-atomic evidences Original Research Article

We use an View the MathML source interaction based in a constituent quark model to study possible View the MathML source quasibound states. Within this model the antiprotonium energy shifts are studied as a signal of such states. The threshold View the MathML source enhancement of J/Ψ decay is also studied, including FSI effects. They can reproduce this enhancement an other View the MathML source threshold enhancements, ruling out their interpretation as signals of bound states.
